Inspection Procedure

INSPECT FUSE (RL DOOR)
1. Remove the RL DOOR fuse from the instrument panel junction block.
2. Measure the resistance of the fuse.
  Standard resistance:
  
  Below 1 Ω
NG: REPLACE FUSE (RL DOOR)

OK: Go TO NEXT STEP.

CHECK POWER WINDOW REGULATOR SWITCH ASSEMBLY (for Rear LH) (POWER SOURCE)

Disconnect the J1 switch connector.

Measure the voltage of the wire harness side connector.
